BALING-PRESS.

Specification of Letters Patent.

Patented Feb. 8, 1910.

Application filed. February 15, 1909. Serial No. 477,987.

To all whom it may concern:

Be it known that I, ERNEST D. SMITH, a citizen of the United States, residing at Lockhart, in the county of Caldwell and State of Texas, have invented a new and useful Baling-Press, of which the following is a specification.

This invention relates to baling presses of that general class shown and described in United States Letters Patent issued to me on the 19th day of January 1904:, under No. 750,232.

The object of the invention is generally to improve and simplify the construction of the plunger operating mechanism, whereby a maximum compression of the hay or other material is obtained with a minimum expenditure of power.

A further object of the invention is to provide improved means for automatically returning the toggle to retracted position after the plunger has been actuated to effect the compression of hay or other material in the press box.

Further objects and advantages will appear in the following description, it being understood that various changes in form, proportions and minor details of construction may be resorted to within the scope of the appended claims.

In the accompanying drawings forming a part of this specification :Figure 1 is a perspective view of a baling press constructed in accordance with my invention showing the plunger starting on its working stroke. Fig. 2 is an enlarged plan view showing the position assumed by the toggle as the plunger nears the completion of its working stroke. Fig. 3 is a similar view on a smaller scale showing the position of the operating levers at the completion of the working stroke. Fig. 1 is a plan View showing the toggle in retracted position. Fig. 5 is a detail perspective view of the pivoted end of one of the links of the toggle. Fig. 6 is a vertical sectional view showing the manner of connecting the pivoted ends of the toggle links. Fig. 7 is a detail perspective view of the plunger retracting arm and the guide therefor.

Similar numerals of reference indicate corresponding parts in all of the figures of the drawings. 7

The improved operating mechanism forming the subject matter of the present invention may be used in connection with any improved form of baling press and by way of illustration is shown in connection with a baling press of the ordinary construction in which 5 designates the compression box, 6 the plunger and 7 the table for feeding the hay or other material to the compression box.

The lower wall of the compression box 5 is extended beyond one end thereof to form a longitudinally disposed support 8 to the free end of which is rigidly secured a substantially tri-angular stationary frame 9 including intersecting bars 10 and 11.

Pivotally mounted at 12 on the bar 10 of the stationary frame is a horse-power 13, also preferably tri-angular in shape and provided with a sweep 14 carrying a swingletree 15 for attachment to a draft animal. Pivotally connected with the plunger and free end of the support 8, respectively, are co-acting toggle links 16 and 17, the inner end of one of which is projected beyond its adjacent pivot and provided with an ofiset portion or arm 17 having a roller 18 journaled therein and arranged in the path of movement of the projecting ends or arms 19 of the horsepower 13, thereby to move the toggle to projected position and effect the compression of the hay or other material in the box 5 when the horse-power is rotated. The inner or over-lapped ends of the links 16 and 17 may be pivotally connected in any suitable manner, but it is preferred to connect the same in the manner shown in Fig. 6 of the drawings in which one of said links is shown provided with a plate 20 having a depending pin 21 arranged to enter a socket 22 in the adjacent link. The plates 20 are secured to the adjacent faces of the links 16 and 17 by bolts or similar fastening devices 23, while the pin 21 is provided with an 0H- set portion or shoulder 24 which bears against a correspondingly shaped seat formed in the socket member 22, thereby to limit the downward movement of the pin. Thus it will be seen that as the sweep 14 is revolved the projecting portions or arms 19 will successively engage the roller 18 and project the toggle to effect the compression of the material in the box 5.

As a means for returning the toggle to retracted position after each compression of the material in the box 5, there is provided a lever or arm 25 having a casting secured to one end thereof and provided with an elongated slot 26 adapted to receive a pin 27 carried by the link 17, the walls of the slot 26 being bent laterally to form an offset pocket 28 adapted to receive the pin 17 when the toggle is moved to retracted position, as best shown in Fig. 4: of the drawings. To the other end of the plunger retracting arm or lever 25 is rigidly secured a plate 29 having its free end bent upwardly and provided with a bearing 30 for the reception of the adjacent end of a roller 31, the opposite end of said roller being journaled in a plate 32 disposed in spaced relation to the extension 30.

The free end of the plate 29 is bent downwardly to form a depending guide lip 3 1 which bears against the inner face of a guide flange 35 of an adjustable plate 36. The plate 36 is provided with elongated slots 37, preferably disposed at right angles to each other and which receive bolts or similar fastening devices 39 by means of which the plate may be adjustably secured to the bar 10 and support 8, respectively. The free end of the flange 35 is curved or deflected laterally at T0 so as to permit the roller 31 to assume the position shown in Fig. a of the drawings, when the toggle is moved to retracted position. The plate 36 is preferably reinforced and strengthened by the provision of an auxiliary plate 11 which extends laterally from one side of the plate 36 and is adjustably secured to the member 10 of the stationary supporting frame, the slots 37 in the main plate 36 and the slots 12 in the auxiliary plate 41 serving to permit adjustment of the flange so that the roller 31 will always be in the path of movement of the arms 19 of the horsepower or sweep. Pivotally connected at- 43 with the outer end of the plunger retracting arm 25 is a second plunger retracting arm 44:, the opposite end of which is pivotally connected with the bolt or stud 12. In order to prevent unnecessary jar or vibration of the machine when the toggle is returned to retracted position a buffer 45 is provided, this buffer being preferably in the form of a spring, the free end of which is provided with a downwardly inclined hook a6 which extends in the path of movement of the toggle link 17 and which acts as a cushion or buffer to prevent unnecessary jar, as before stated. Thus it will be seen that when the parts are in the position shown in Fig. 1 of the drawings and an initial rotary movement is imparted to the sweep in the direction indicated by the arrow in said figure, the arm 19 will engage the roller 18 and force the toggle links 16 and 17 inwardly in the direction of the support 8 and to the position shown in Fig. 2 of the drawings, a further rotary movement causing the arm 19 to move the links to a position substantially in alinement with each other, as best shown in Fig. 3 of the drawings, thereby to effect the compression of the hay or other material in the box 5.

As the horse-power or sweep approaches the position. shown in Fig. 3 of the drawings, the roller 18 will be disengaged from the adjacent arm 19, while the latter will bear against the roller 31 and move said roller together with. the arm to the position shown in Fig. 'l of the drawings, thus exerting a lateral pressure on the toggle and moving the latter to retracted position and in the path of movement of the adjacent arm 19 of the sweep or horse-power so as to be again actuated to compress the material in the press-box when a further rotary movement is imparted to the sweep.

From the foregoing description it is thought that the construction and operation of the device will be readily understood by those skilled in the art and further description thereof is deemed unnecessary.
